Time to Take a Closer Look!

A student looks at what he caught in the Rio Grande which included dragonfly nymphs as an adult dragonfly goes past


Look in the ‘Materials’ tab to find the Watershed Watch Order Key!

Use the Watershed Watch Order Key to help identify the organisms and the Benthic Macroinvertebrate Sorting & Recording Sheet to document what you discover! Both are located in the ‘materials’ tab. Identify as much of the sample as possible. Tally the number of insects in each category at each station in a table. Use the calculations in the data interpretation section to develop findings about the condition of the benthic community and river that supports the critters.

This level of analysis provides a general idea of the richness of biodiversity of the benthic macroinvertebrate community. Key indicator insect groups include mayflies (Ephemeroptera), stoneflies (Plecoptera), and caddisflies (Tricoptera).
